A key reason Freud has gone out of style is that science has found that his psychology is mistaken in key ways. Freud believed that everything in adult psychology is an elaboration of something already there in the infant mind. That is dubious, but even if you accept it, there is the problem that Freud did not investigate infant psychology directly, but instead assumed it is basically irrational, asocial and radically out of touch with reality. In recent decades infant psychology has been the subject of extensive empirical study, and it turns out to be much different from what Freud thought. See, for instance , <i>The Scientist in the Crib</i> by Gopnik, Meltzoff and Kuhl.
